I feel it's one of the many signs that a man is prepared in everyway for marriage, spiritually, physically, financially, emotionally, etc. I don't put a dollar figure on it, but more of a general guideline of the man providing--providing love, protection, adding to the women's worth. Women want security in every way or resentment can easily build up if the woman is the breadwinner, I feel. My first love made very little money and I was with him for years, but I don't want to wear the pants. I was raised in a traditional and loving home where the man provided, and ultimately, that is one of the many things that is just inherent in a woman's soul to desire in her mate. Why would he be comfortable in any other role when that is the role that he is called to fulfill from God. The woman is called to her role and I don't resent it but rather look forward to living it.
There's many scriptures on how the man is to provide for his family. God is a God of order and men should take their rightful role in the family/household. That is very attractive to me. Men love respect from their mate and I don't have any problem giving that, but the man has to earn it and be a man of integrity, not just want it as a given.
Hope this helps,
I don't the number matters, but we all need to realize that a nice style of living in one state is almost impoverished in another. The amount is relative to where you reside and the style of life you have....Los Angeles, San Francisco, Boston, New York, Chicago are all examples of cities that require very signification amounts of money to just get by and provide a very middle class or lower lifestyle. That same amount of money will allow you to live like a king or queen in another part of the country.
Does income matter? I think this is a question/answer that points to the character of the person. Some people may want a spouse who earns a certain amount because they want to live a particular life style with a lot of nice things, vacations, etc. Other people may be more content with the simple things in life and satisfied with a spouse who considerably earns less. Most people probably fall in between. Think about what is important to you about your life, where you want to be financially and look for someone who wants the same things.
For me, its important that a person be able to live within their means and learning to be content with what you have.
